FUNNEL.

Application filed .Tuly 26, 1926. Serial in. 124,827.

This invention relates to funnels for-"the filling of bottles and likecontainers and has for its principal object to provide a device of thischaracter which is adapted to cut off the flow when a liquid has reachedthe desired height in the said container.

A further object is to give visible indication of the rise of the liquidto a certain point.

This indicating feature is a great advantage when the bottles beingfilled are of opaque glass, or have labels which obscure the view of thefilling process.

The foregoing, together with other. objects and advantages will be fullydescribed in the following specification and illustrated in theaccompanying drawings, in which:

Fig. l is a perspective view of the device in its simplest form.

F 2 is a sectional. view of the funnel inserted in the neck of a bottleand with the plunger in its lowest position.

Fig. 3 is a similar View to Figure 2, except that the plunger is shownin its highest position and the valve closed.

Fig. 4 is a section on the line 4-4 of Figure '2.

Fig. 5 is a sectional view of the device in a modified form and showinga calibrated indicator.

Fig. (3 is a side view of the indicator element showing method ofattachment to the plunger rod.

Referring to Figure 1, the device comprises a conical receiver '10having a cross supporting element 11, which element has a central diskplate 12 which is perforated for the passage therethrough of the plungerrod 13. Extending downward from the base of the receiving element isatapered spout 14 having embossed side portions as shown at 15, 16 etc.At the extremity of the spout- 14 is a flanged valve seat 17.

On reference to Figures 3 and 4, a guide member 18 may be seen inposition just above the valve seat. This member serves to hold theplunger rod in its central position. The purpose of the embossed sidesis illustrated in these views. This purpose being to permit of theescape of air between the neck of the bottle 19 and the spout of thefunnel.

Referring now to Figure 2 in particular, the valve head 20 is seensecured to the plunger rod 13. This valve head may be constructed ofcork, or other fioatable material, or may be of hollow form with aninternal air space to gi veyitthe required displacement. The head 20 isbeveled at the topportion 21" to fit within the valve seat when in itsraised position and is provided with a horizontal seat 21 which isadapted to engage the edge of the lower extremity of the funnel. A ring21 is provided at the top of the plunger which acts as astop member andat the same time affords a means for lifting the device from the bottlewhen it also serves to draw the valve head securely within the seat thusensuring against leakage, or dripping of the liquid remaining in thereceiving element. When the funnel is removed from a'bottle while fullof liquid by lifting the same by considerable force applied on the head20 which tends to drive thelsame in the end of the funnel. This actionis restrained by the engagement-of the with the seat 21" which aids insupporting the weight of the thereof.

When placed within the neck of a bottle, the floatable valve head firsthangs suspended, but when the liquid 29 rises to the point of contacttherewith as shown inFigure 2 at 22, it rises with the said liquid untilit comes to rest within the valve seat 17, thus stopping any furtherflow through the spout 14, this stage is illustrated in Figure 30f thedrawings. The funnel may now be lifted from the bottle by means of thring 21 and the process is completed.

The calibrated indicator 22 shown in Fi ure 5 is constructed as follows.A flat bar 23 is graduated as shown at 24 and is secured to a flattenedportion of the plunger rod 13 as shown at 25. In this case rivets areused as shown at 26 and 27, but spot welding, or other method may beemployed if desired. A pointer 28 is bent upward from, oresecured to abar of the cross supporting element and acts in conjunction with thecalibrated indicator bar. 7

While I have shown the preferred forms of my invention, I do not wish tobe held rigidly to the exact details of construction as shown, but claimthe right to such minor modifications as may come within the scope ofthe appended claims.

Having thus described my what I claim as new and desire to LettersPatent, is as follows:

In a device of the class described, a funinvention, secure by the ring21, there is edge of the funnel."
